WINDOW-VENTILATOR.

I Specicaton of Letters Patent.

Patented 0ct. 10, 1916.

Application led'January 3, 1916. Serial No. 70,059.

il 0 all whom t may concern:

Be it known that I, URIAi-I R. HARDING, J r., a citizen of the United States of America, and a resident of Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Vindow-Ventilators, of which the following is a specification.

This invention relates to improvements in Ventilating devices for use in windows and has for its object the provision of a device of this character which may be permanently attached to the window frame and will move into its operative position when the lower sash is raised and while in such position will leffectually prevent the admission of rain and snow into the room.

The invention consists of a framework pivoted at its upper and outer corner to the window frame and having extension members adapted to move into a position below the lower sash when the latter is raised, and to be engaged by the said sash when lowered to move said framework into its inoperative position.

The invention further consists of certain novel features of construction and arrangement of parts which will be fully understood by reference to the description of the drawings and to the claims hereinafter given. l Y

Of the drawings: Figure 1 represents an outside elevation of a window provided with a ventilator embodying the principles of the present invention. Fig. 2 represents an inside elevation of the same. Fig. 8 represents a horizontal section of the same on line 3-3 on Figs. 1 and 2. Fig. 4 represents a vertical section of the lower portion of the same on line 4 4 on Fig. 3 with the Ventilating device in its closed position, and Fig. k5 rep resents a similar section with the ventilating device in its open position.

Similar characters designate like parts throughout the several figures of the drawings.

ln the drawings, 10 is a window frame provided with an upper sash 11 and a lower sash 12. To each of the inner sides of the frame 10 is secured a platev13 having at its upper end a pivot 14 extending through the upper and outer corner of a plate 15.

The pivot member 14 is located closely adjacent to the inner face of the lower sash 12. Each plate 15 is provided at its lower end with an extension 16 inclined outwardly from the front edge 17 of said plate 15, To

each of the plates 15 is pivoted at 1S one part of an inclined member 19 having an end flange 20 and )rovided at ,its inner upper end with a deflecting portion 21 which is in vertical position when the Ventilating device is in operation, as indicated in Fig. 5 of the drawings. Each plate 18 is provided with a guard 22 with which the edge 17 of the plate 15 engages to limit the outward movement of the plates 15 about their pivots 14.

The rear edge of each plate 15 is provided with an inturned lip 23 which is adapted to be engaged by an outwardly turned lip 24 on the flange .20 to limit the inward movement of the members 19 when the ventilating device is in its operative position. The members 19 telescope into each other so as to adapt the ventilating device for various widths of windows.

Above each plate 13 is located an eye 25 through which extends a flexible member 26 one end of which is secured to an eye 27 in the lower sash 12 while the other end is secured at 2S to an end flange 2O formed integral with a member 19.

When the lower sash 12 is in its lowest position this flexible member 26 will be moved lengthwise through the eye 25 and cause the members 19 to be moved about the pivots 18 into closed position as indicated in Fig. 4 of the drawings.

Vhen the lower sash 124 is raised the inem bers 19 will drop by their own weight into the position shown in Fig. 5 of the drawings. Said members 19 in so doing move about the pivots 18. When the lower sash 12 is raised the plates 15 will move about the pivots 14 until the edge 17 engages the guard 20. At this time the extensions 16 will assume a position beneath the lower sash 12. Vhen this sash 12 is lowered its edge will engage with the inclined extension 16 and force the plates 15 about the pivots 14 into the position indicated in Fig. 4 of the drawings.

The airv admittedV into the room beneath the raised sash 12 will move along the upwardly inclined face of the members 19 and strike the deflecting portion 21 thereof and be forced into the upper part of the room. When the sash is raised and it commences to storm, any rain or snow that might enter beneath the sash would be collected on the inclined surface of the members 19 and run 0H on the outer portion of the window frame.

If any rain or snow should enter the interlocking portion 23, 24 of the plates. l5 and flanges 20, said rain or snow would Vbe car` ried down the inclined groove formed by the inturned portion 23 and delivered on the outer portion of the window frame.

This makes a very effective window ventilator which may be permanently attached to the window frame and will be operated automatically'by the raising and lowering of the lower window sash. When in operation the air entering beneath the lower sash will be deflected into the upper part of the room.

It is believed that the operation and many advantages of this invention will be fully understood from the foregoing description.

Having thus described my invention, I claim:

l. In a window ventilator, the combination of a swinging member having end flanges provided at their lower ends with narrow extensions having inclined edges adapted to be engaged by a window sash, and pivot members extending through the outer and upper corners of said flanges into a window casing closely adjacent to `the lower sash.

2. In a window ventilator, the combination of a swinging member having end flanges provided at their lower ends with narrow extensions having inclined edges adapted to be engaged by a window sash, and pivot members extending through the outer and upper corners of said flanges into a window casing closely adjacent to the lower sash; and a guard to limit the outward movement of said pivoted member.

3. In a window ventilator, the combination of a swinging member having end flanges pivoted at their upper and outer corners to a window casing; and a narrow extension on said member having an inclined edge adapted to be engaged by the lower sash in said casing to swing said member about its pivots.

4. In a window ventilator, the combination of a swinging member having end flanges pivoted at their upper and outer corners to a window casing; a narrow extension on said member having an inclined edge adapted to beengaged b y the lower sash in said casing to swing said member inwardly about its pivots; and means for limiting the outward movement of said member when said lower sash is raised.

5. In a window ventilator, the combination of a swinging member having end flanges; and a plate pivoted at its upper and outer corner to a window sash and provided with an extension to the lower end of which said flanged member is pivoted, said extensions being adapted to be engaged by the downward movement of the lower sash to swing said member about its pivots.
